Power Inlet
The switching power supply will operate with line volt-
ages between 100 and 240 VAC. The inlet socket is a
standard 3-pin C14 type that accepts any cordset with a
C13 connector.
Cooling Fan
The microprocessor monitors the internal temperature
of the processor and controls the variable speed fan as
needed. Operating temperature is very well regulated.
RS-232 and Ethernet Ports
Each host assembly provides RS-232 and Ethernet
ports for communication with the microprocessor. The
ports can be utilized simultaneously for monitoring,
setup and control.
ASPEN Ports
This gigabit bus transports audio and data from one
board to the next through CAT-6 cabling and RJ-45 con-
nectors. Processors are normally installed with the Mas-
ter unit on top and Slave units below it. The cabling is
then connected from the uppermost jack on one board
to the lowermost jack on the unit just above it. See page
9 for more information.
Balanced Mic/Line Inputs
Every mic/line input is a balanced, differential type with
adjustable gain from -10 to +60 dB. Connectors are a
standard 5-pin Phoenix depluggable type with adjacent
channels sharing a common ground.
Balanced Outputs
All outputs are a balanced, differential type. Channels 1
through 8 on each board are nominal line level outputs
with gain adjustment from -60 to +20 dB. Channels 9
through 12 on each board are also line level outputs
with switchable attenuation of -20 and -40 dBu nominal
levels (mic level), with gain adjustment from OFF to +20
dB.
Programmable Input and Output Ports
Programmable inputs and outputs used to control
levels, settings, indicate the current state of a program-
mable input and control a variety of other parameters.
ASPEN Bus Data/Audio Ports
These RJ-45 jacks carry the audio signals and con-
trol data between each system board as well as units
stacked together.
Remote Control
These RJ-45 jacks provide interfaces for RCWTH4
remote control units. Each jack is assignable to CODEC
1 or 2, or to the telephone line.
Conferencing Inputs and Outputs (Codecs)
Analog audio input and output connectors for the Codec
ports.
Telephone Set/Line
RJ11 jacks for connecting a standard telephone line
and a single-line telephone set.
Power Amp Outputs
The amplifier is designed to run continuously (idle or
with a load) without heat buildup, making it ideal for
permanent installations where prolonged operation is
required.
